Unit 3 Celebrities Lesson1 Spring Festival课时作业第一节、阅读理解阅读下列短文，从每题所给的四个选项（A 、B 、C 和D）中，选出最佳选项，并在答题卡上将该项涂黑。
AThere are many ways to define fame. But one of them, surely, is to see your name in lights above bustling New York streets. A Chinese writer saw just an illumination （光源）in July when his name appeared on the big screen in Times Square. For Liu Zhenyun, it was a spectacular and fully-deserved promotion of his latest book, Laughter and Tears: A Novel.Liu, one of the best-selling authors of novels in contemporary China, has penned a number of popular works,including Someone to Talk To,Remembering1942,and I DidNotKillMy Husband.His works have been translated into more than 28 languages, and Someone to Talk To was awarded lhe 2011 Mao Dun Literature Prize."Laughter and Tears:A Novel "can be worthily called another ' high peak' after Someone to Talk To:'Zhang Xudong, a professor of comparative literature and East Asian studies at New York University, says. The novel is based on the folklore of a legendary figure Hua Emiang, and describes the paintings of the narrator's uncle, telling of the humor and life of people in Yanjin, Henan province, Liu's hometown.In the book, everyone from Yanjin is humorous and can tell excellent jokes. Hua Emiang, the spirit of a widow waiting eternally for her husband, as in Yanjin folklore, will come into people's dreams. In this state she will ask them to tell her a joke. If she thinks the joke is boring, she will instruct them to carry her to a place where she candrink spicy soup. But they die in the effort as she crushes them following her transformation into a mountain. However, if she likes the joke, she will give them a persimmon (柿子). As a result, people from Yanjin tell really good jokes.Corriere della Sera,an Italian newspaper, called Liu "the Kalka of Beijing". In 2018, Liu was awarded France's Knight of the Order ofArts and Letters.An author at Kirkus Reviews, a book review site in the United States, writes, "Liu has written a masterful tale that will make you laugh even as you feel hopeless". Liu's tragedies often have a feature of comedy and his comedies are also like tragedies. He tells many jokes and ridiculous stories in his books, and you will laugh when you read them. However, the truth behind the jokes could be cruel and sorrowful.1 ．Why did Liu Zhenyun's name appear on the big screen in Times Square?A ．Because he enjoys great reputation.B ．Because his new book has been sold out.C ．Because he is eager to establish his fame.D ．Because he wants to promote his best book.2．What would Zhang Xudong probably agree with?A ．Liu Zhenyun is a legendary figure.B ．No book beats Someone to Talk To.C ．Liu's novels belong to comparative literature.D ．Laughter and Tears:A Novel is worth reading.3．In Liu's latest book,Hua Emiang gave the joke-tellers a persimmon as a(n).A ．PunishmentB ．assignmentC ．awardD ．warning4 ．What could be the best title for the passage?A．Liu Zhcnyun,a Master of TragedyB ．Zhang Xudong, the Kafka ofBeijingC．A Writer with Tale to Tell Pens a New BookD ．A Book Was Awarded Mao Dun Literature Prize【参考答案】ADCCBA joint research team recently have developed a new electronic skin that is similar to human skin in strength, durability and sensitivity. The skin or e-skin may play an important role in next-generation personalized medicine, soft robotics and artificial intelligence.“The ideal e-skin will mimic (模仿) the many natural functions of human skin, such as sensing temperature and touch, accurately and in real time,” says leading researcher Yichen Cai. However, making suitably flexible electronics that can perform such delicate tasks while also used repeatedly is challenging, and each material involved must be carefully engineered.Most e-skins are made by putting an active sensor on the surface that attaches to human skin. However, the connection between them is often too weak, which reduces the durability and sensitivity of the material; otherwise, if it is too strong, it won’t be flexible enough, making it more likely to break the circuit.“The landscape of skin electronics keeps shifting at a remarkable pace,” says Cai. “The discovery of 2D sensors has accelerated efforts to turn these quite thin but strong materials into functional, durable artificial skins. ”The new man-made skin built by the researchers could sense objects from 20 centimeters away. It co uld further make a quick response when touched in less than one tenth of a second. “It is a striking achievement for an e-skin to maintain toughness after repeated use,” said Shen, “which mimics the softness and rapid recovery of human skin.”This type of e-skin could monitor a range of biological information, such as changes in blood pressure, which can be sensed from movements of arms and legs. This data can then be shared and stored on the cloud via Wi-Fi.“One remaining problem to the wide spread use of e-skins lies in mass production of high-resolution sensors,” adds group leader Vincent Tung, “however, the latest technology offers new promise.”5. What’s the feature of the new e-skin?A. It is flexible and sensitive.B. It is almost the same as human skin.C. It has fragile electronics.D. It has proved important in areas like AI.6. What can the new e-skin do?A. It can rapidly react to touches.B. It can change human’s blood pressure.C. It can heal the wounded skin quickly.D. I t can adjust human’s temperature.7. What does the underlined word “striking” in paragraph 5 probably mean?A. Slight.B. Noticeable.C. Well-known.D. Insignificant.8. What is the best title for the text?A. A Breakthrough in High TechnologyB. Man-made Skin ImprovedC. E-skin, a Promising BusinessD. The Wide Spread Use of E-skin【参考答案】AABB第二节、七选五阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

【spring-boot】springboot整合quartz实现定时任务
【spring-boot】springboot整合quartz实现定时任务在做项⽬时有时候会有定时器任务的功能，⽐如某某时间应该做什么，多少秒应该怎么样之类的。
spring⽀持多种定时任务的实现。
我们来介绍下使⽤spring的定时器和使⽤quartz定时器 1.我们使⽤spring-boot作为基础框架，其理念为零配置⽂件，所有的配置都是基于注解和暴露bean的⽅式。
2.使⽤spring的定时器: spring⾃带⽀持定时器的任务实现。
其可通过简单配置来使⽤到简单的定时任务。

The Spring of Youth - 作业
THE SPRING OF YOUTHAct 1[SCENE Paris Hotel. 4:50 pm. Because of Maggie, everyone's eyes popped out of their heads in surprise. Those astonishing faces belonged to Maggie's high school classmates. There were twenty faces in this room, but nineteen of them were covered with age spot and crow's-feet, totally like an ugly gray rat. Only Maggie, with rosy cheeks and profound big eyes, was just like a charming little bird in her booming age. However, God and everyone there tonight, knew she had lived in this world for 42 years! Maggie suddenly became the star of this party but a middle aged couple didn't notice her yet. They were sitting in the corner and chattering with each other. ] Joe: [Pointing at a lady near the window surprisingly] Is that Maggie?Judy: [Raising her head frivolously and arrogantly] No way, she has disappeared for years since you divorced her and got marry with me. I am a winner but she is such a loser. How dare she come here and compete with me again. Hahahahah........[Judy was laughing so boldly and presumptuously that she didn't realize Maggie already came over and just stood beside her. Seeing Maggie, Joe began coughing unnaturally and trying to stop Judy's laugh]Joe: [Puffy-eyed on Maggie, standing up immediately and turning into a greasy manner] Oh my God, are you Maggie? Y ou look so young. It seems that you are never growing old. Oh, you are still such a beautiful creature. I haven't seen you since we get divorced. How are you? I miss you very much. And do you......Maggie: [Interrupting Joe without even looking at him and looking right at Judy] Judy, long time no see. Y es, can't you guys recognize me? I'm Maggie and I come back. [Then with a faintly mocking smile, she turned around and walked away.]Judy: [Furiously took a long swallow of wine and muttered out of discontent] What the hell is this? [Finally calming herself down, she fished out their hand mirrors and touched their wrinkles.] Maybe I need freshen up, I should go to the lady's room.Act 2[SCENE Lady's room of Paris Hotel. Sitting in front of the mirror Judy's memories went back to 20 years ago. At that time, she was Maggie's best friend. They went to Maggie's hometown. Maggie pointed to the endless mountains and told her there was a legendary spring that could bestow perpetual youth. Now even God knew she was thirst for youth, for beauty desperately. She needed her soft lips and smooth skin to maintain her perilous marriage, her gloomy career and her crumbling happiness. Her eyes began to give out a harsh light of hope. She must find that legendary spring and drank it. ]Judy: Actually it is true, there really is a spring! So, that legend is true, isn't it? The spring of youth is real. I need it. I need it!! [She whispered to herself secretly, then quickly looked around to make sure that on one else peeked this.] [The door yielded to a gentle push. The crazy flame in Judy's eyes immediatelydisappeared. Maggie came in. With a surprising and guilty look, Judy didn't say anything. So did Maggie.]Judy: [Bracing herself and breaking the ice first] I used to be your closet friend, Maggie. And I know I really did something wrong to you but please forgive me. Let's forget it! I will give you a lot of money and everything you want. Please forgive me.Maggie: [Smiling scornfully and wagging her head ] Forgive you? Are you kidding? How could I forget everything, How could I forget you, as my best friend, steal my husband, my career and my happiness? Oh, I know, you must want something from me again. Tell me what you want!Judy: [Acting as if she were mad] Twenty years ago, you told me there was a legendary spring in your hometown that could bestow perpetual youth. Please tell me the exact address of it. I will give you anything I have. Just tell me where is the spring of youth, please, please…[Judy began crying.][Maggie gazed at her silently and casted her thoughts back to 15 years ago. At that time, Judy's fantastic charisma captured all the men in the world, including Maggie's husband, Joe. Suddenly a very cruel idea burst into Maggie's mind.] Maggie: I want 100,000 dollars.[Judy nodded with out hesitation]Maggie: I want your company.[Wavering between yes and no, finally Judy nodded her head again.]Maggie: I want my Husband, Joe, back![Judy knelt down and after a long time, she surrendered to Maggie's temptation.] Maggie: Look, look at the mirror. Now you are as panic-stricken as a stray dog. And now I find I didn't mad at you at all but even I start to pity you. Y ou love nobody but yourself. Here is the spring, go and get it and never come back.[Chucking a slip of paper at Judy's face, Maggie left the lady's room. Gazing at her lessening figure, Judy grabbed hold of it immediately. Half an hour later, Maggie and her flaming Ferrari vanished in the Paris Hotel.]Act 3[SCENE One Month Later. Raining slightly. A dark and damp lane. Maggie opened her door. A middle-aged woman was waiting for her. With that woman lifting her head, a face, which was exactly like Maggie's but much older and more sophisticated, was shown up. She said nothing but handed over an extraordinarily heavy bag full of money.]Maggie: [Took it quietly and hove a sigh of relief] Finally I can give the name of "Maggie" back to you. Have you see today's newspaper? Judy died.Middle-aged woman: Thank you very much, girl. Carrying your money, never come back.[Then, carrying that extraordinarily heavy bag, the so-called "Maggie" left this lane in a hurry. And so did our real Maggie. But our Maggie seemed to forget something, for she suddenly stopped in a newsstand and bought a piece of evening paper. There was an average-size obituary in it.]Maggie: [She read loudly] The memorial meeting of Mrs. Judy Blond will beheld in....[She smiled, for disdain or contempt. Once again she recollected that legend of her hometown. Through the endless mountains, you would find a legendary spring effervescing with bubbles. The water was as sweet as wine, as fragrant as perfume. Only a sip of it might make you keep young forever…Oh, no,no, no. The fact was after you drank it, the egg of that nameless deadly creature would be hatched out by your body temperature, and then its tentacles would pierce into your heart...]。
SpringBatch中文参考文档V3.0.6-1SpringBatch介绍
SpringBatch中⽂参考⽂档V3.0.6-1SpringBatch介绍1 Spring Batch介绍企业领域中许多应⽤系统需要采⽤批处理的⽅式在特定环境中运⾏业务操作任务。
这种业务作业包括⾃动化，⼤量信息的复杂操作，他们不需要⼈⼯⼲预，并能⾼效运⾏。
这些典型作业包括：基于时间的事件处理(例如：⽉底结算，通知或信函)；重复的、数据量⼤的、业务逻辑规则错综复杂的定期任务(例如：保险盈利决策和利率调整)；来⾃内外部不同应⽤系统的信息集成任务，这些信息需要进⾏格式化、校验，并通过事务的⽅式处理成为系统可⽤的记录。
批处理程序就是⽤来处理这种数以亿计的企业⽇常事务。
Spring Batch是⼀个轻量级的，全⾯的批处理框架，旨在帮助开发⼈员构建出健壮的⽤于处理⽇常事务的企业级批处理系统。
Spring Batch 构建于POJO和Spring框架，开发者容易上⼿，现有的优秀企业级服务也能融合进来。
Spring Batch不是⼀个调度框架。
当前开发市场上有许多优秀的企业级调度器，包括付费软件和开源软件，例如Quartz, Tivoli, Control-M等。
Spring Batch的设计意图不是来替换它们，⽽是配合这些调度器协同⼯作。
Spring Batch提供处理⼤数据的可复⽤的核⼼功能，包括⽇志/跟踪，事务管理，Job程序统计，job重启，job跳转和资源管理，它同时也提供先进的技术服务和特性，即通过优化和分区技术使得批处理作业达到⾼容量和⾼性能。
⽆论简单的，复杂的还是⾼容量的批处理任务都可以利⽤该框架的可扩展性来处理⼤量的信息。
1.1 背景当开源软件项⽬和相关的社区重点关注⽹络和基于SOA消息的体系框架时，java领域仍然缺少⼀个可复⽤的批处理框架，企业应⽤仍在当前的IT环境中处理这样的批处理事务。
标准化、可复⽤的批处理架构的缺失导致IT企业各⾃开发了⼀次性的、并只针对本企业内部系统的解决⽅案，⽆法复⽤。
